GM El Heraldo was flying. That in and of itself wasn't too odd, bur he was flying high enough in the air that all he could see were clouds. A moment later he flew out of the cloud bank, looked down, and realized he was miles above the ground, and moving fast! All he could see below him was a lonely line of highway paralleling a ribbon of coastline. A quick fly-by confirmed that he was heading south -- and in South Carolina! Why in the world would he be flying so high and so fast due south? becau
